Cost Effective Asset Maintenance Requires GIS & Work Management System Integration
Goal 3: To Perform Operational Analysis
Although not the specific topic of this paper, integration of WMS with SCADA (supervisory
control and data acquisition) provides ability to:
-
Download SCADA runtimes, cycle counts, and meter reads for specific assets to
trigger work activities based on a pre-defined parameters
-
Perform modeling of geographic areas or system performance to see what is going
on (flows, flow rates, pressures, etc.)
-
Provide visual status of geographic areas or systems
Goal 4: To Meet Regulatory Challenges
Two regulatory drivers, GASB 34 and CMOM, reinforce the need for an integrated
GIS/WMS. In summary, these regulations require identification and tracking of all assets,
and documentation of all work performed Each is described in further detail below.
GASB Statement No. 34
Governmental Accounting Standards Board Statement Number 34 (GASB-34) requires local
governments and municipalities to know how much they spend on infrastructure
construction, borrow to finance it and how the infrastructure is maintained. Compliance
with GASB-34 requires the ability to identify assets and report on their value.
This requires practices and enabling technology to systematically identify, track, and manage
assets. All asset related work (maintenance, repair or inspections) must be documented. The
design implication is that asset inventories must be integrated with work management.
CMOM
Capacity, Management, Operation, and Maintenance (CMOM) is the Environmental
Protection Agency's (EPA) proposed regulation on sewer collection systems.
Documentation is a critical element of CMOM compliance. Basic tenets of this proposed
regulation include:
-
Sewer System Documentation - Measure activities for capacity management,
mapping and map maintenance, facilities and equipment, trending and analysis of
flow volumes and spill histories, routine operations and maintenance (O&M)
activities, short- and long-term rehabilitation and replacement plans, training, and
maintenance parts inventories.
-
Asset Management-Includes a complete inventory of assets and procedures for
documenting and determining their condition over time. Procedures for identifying
near- and long-term repair and upgrades including documentation of work. Ability to
perform historical analysis and trending of sanitary sewer overflows. Identify
hydraulic (capacity) and physical deficiencies and prioritize responses. Ability to
identify preventive and predictive maintenance requirements and to manage the areas
or systems based on historical performance data.
-
Work Management- Includes development of preventive maintenance program.
Identifying routine preventive maintenance activities and inspection schedules and
documentation of maintenance/inspections performed.
-
Materials Management - Includes managing maintenance supporting parts and tools
inventories plus keeping equipment in working order.
A WMS integrated with GIS positions organizations with distributed assets to compile asset
inventory and work related data for the infrastructure in support of GASB-34 and CMOM
requirements.
